I might go to the UFO event.
A little worried about the bad rep of how the UFO is run.

Side note,
I use to drift most of my cars, wasn't really any good but had fun.
Now I'm trying to run grip.
Car is stock everything except brake pads and borrowing some strut bars
I've tracked the car at Thunderhill and Laugna Seca both times with full aids on.
Then I ran at the American Auto-X last weekend with traction control off and was sliding all over the place.

I don't have a big budget.
1. I'm wondering if I should run the stock tires till they are done or upgrade to either Dunlop Z2s or Bridgestone RE-11As 225-45 17s? Tires will be track and DD. Without the strut bars this will keep me in RTR class. I'll also upgrade with the crash bolts and front sway bar.
2. I don't want to buy new rims because if I do I'd want to go with 17x9s, but that'll bump me up to STX.

I could possible afford 17x9 RPF1s tires, and sway bar, but would that not be enough for STX class?
Should I stick with my stock rims and upgrade tires or not, and would this be better to learn from than upgrading the size of tire and going to coilovers?
